Saggie Haim developed an enhanced cost workbook for the Azure/Azure-Sentinel repository, focusing on improving budgeting accuracy for organizations using Defender for Cloud Plan 2. He introduced a licensing-aware cost display and implemented a new ingestion benefit parameter, allowing users to estimate grants and reflect licensing-related savings directly within the reporting interface. Working primarily with JSON for data configuration, Saggie updated AzureSentinelCost.json to incorporate these financial calculations, supporting more precise cost management. His work emphasized data modeling and reporting, delivering a targeted feature that addressed real-world budgeting needs without requiring major bug fixes or extensive changes to existing infrastructure.
